Detailed Description
AST Super Factory shared by TreeParser and Parser.This super factory maintains a map of all AST node types to their respective AST factories. One instance should be shared among a parser/treeparser chain.
- Todo:
- check all this code for possible use of references in stead of RefAST's.

Constructor & Destructor Documentation
|
Make new factory. Per default (Ref)CommonAST instances are generated. We use delegation to share code (and have only one bit of code to maintain) rather than subclassing or superclassing (forces AST support code to be loaded even when you don't want to do AST stuff). This class collects all factories of AST types used inside the code. New AST node types are registered with the registerFactory method. On creation of an ASTFactory object a default AST node factory may be specified. When registering types gaps between different types are filled with entries for the default factory. Definition at line 38 of file ASTFactory.cpp. References ANTLR_USE_NAMESPACE, default_factory_descriptor, and nodeFactories. |
|
Initialize factory with a non default node type. factory_node_name should be the name of the AST node type the factory generates. (should exist during the existance of this ASTFactory instance) Definition at line 48 of file ASTFactory.cpp. References ANTLR_USE_NAMESPACE, default_factory_descriptor, and nodeFactories. |
|
Destroy factory.

Make a tree from a list of nodes, where the nodes are contained in an ASTArray object. The ASTArray is deleted after use.
Definition at line 275 of file ASTFactory.cpp. References ASTArray::array, make(), and RefAST. |
|
Make a tree from a list of nodes. The first element in the array is the root. If the root is null, then the tree is a simple list not a tree. Handles null children nodes correctly. For example, make(a, b, null, c) yields tree (a b c). make(null,a,b) yields tree (nil a b). Definition at line 231 of file ASTFactory.cpp. References nullASTptr, and RefAST. Referenced by make(). |

Set a new default AST type. factory_node_name should be the name of the AST node type the factory generates. (should exist during the existance of this ASTFactory instance). Only change factory between parser runs. You might get unexpected results otherwise. Definition at line 297 of file ASTFactory.cpp. References default_factory_descriptor. |
